1. The problem asks to identify which system of inequalities could represent the graph shown in the xy-plane. 2. The inequalities involve either $y$ or $x$ with boundary lines at $3$ or $-3$. 3. To understand the system, recall that $y \geq 3$ means the region above or on the line $y=3$, and $y \leq -3$ means the region below or on the line $y=-3$. 4. Similarly, $x \geq 3$ means the region to the right or on the line $x=3$, and $x \leq -3$ means the region to the left or on the line $x=-3$. 5. The system $y \geq 3$ and $y \leq -3$ is impossible because $y$ cannot be simultaneously greater than or equal to $3$ and less than or equal to $-3$. 6. The system $y \leq 3$ and $y \geq -3$ represents the horizontal strip between $y=-3$ and $y=3$ inclusive. 7. The system $x \geq 3$ and $x \leq -3$ is impossible for the same reason as in step 5. 8. The system $x \leq 3$ and $x \geq -3$ represents the vertical strip between $x=-3$ and $x=3$ inclusive. 9. Therefore, the graph could represent either the horizontal strip $y \leq 3$ and $y \geq -3$ or the vertical strip $x \leq 3$ and $x \geq -3$ depending on the shading. Final answer: The system of inequalities $y \leq 3$ and $y \geq -3$ or $x \leq 3$ and $x \geq -3$ could represent the graph.
